This paper tests whether capitated payments to Medicaid managed care plans induce to plans strategic undercutting of treatment for specific diagnostic groups. I focus on treatment (measured by length of stay and cost) in acute care hospitals in Massachusetts. I use a differences-in-differences-in-differences approach, where the third differences compare treatment patterns between managed care plans that receive capitated payments with those that do not. I find that the first reduce treatment significantly more to mental health patients than to patients in other disease groups, whereas the latter reduce hospital resource use more uniformly across disease groups. These results highlight the importance of using payment mechanisms in public programs that reflect the variability in costs of beneficiaries.Received: September 2002, Accepted: May 2003, JEL Classification:

This paper measures the utility gains from exploiting short-run predictability in the volatility of stock returns in a dynamic model in the the presence of transaction costs, short-selling constraints and estimation risk. We find that utility gains are quite significant, both ex ante and out-of-sample. 相似文献

In the today′s changing environment, firms are hardly competing with each other to achieve a competitive advantage that can differentiate them from others and improve their organizational performance. In this sense, it is crucial to develop corporate entrepreneurship and promote strategic variables that foster it.The aim of this paper is to highlight the importance of different technological variables (top management support to technology, technological skills and technological distinctive competencies) and organizational learning on corporate entrepreneurship, and thus analyze the influence of corporate entrepreneurship on organizational performance in the context of technology firms.A sample of 160 European technology firms was selected from the database Amadeus in 2009 with CEOs as our main informants. The hypotheses studied are empirically confirmed by using a hierarchical regression model. 相似文献

Increasing academic attention is being given to the role of management gurus, consultants, managers and academic researchers in the international diffusion of Western management ideas. This is part of wider debates on knowledge, power and globalization. Relatively little attention has been paid to the mechanisms through which diffusion takes place and, in particular, the role of academics as lecturers and business schools as disseminators of management knowledge at home and abroad. This paper draws on the authors' personal experiences and perceptions of teaching on an Executive MBA programme in Malaysia and those of their students.
Management education is growing rapidly in many regions of the world and has become highly commodified and commercialized, with Western universities competing in emerging markets for potentially lucrative local opportunities and foreign students or 'consumers'. Accordingly, the process of diffusion of Western management ideas is examined through a consumption perspective which treats the foreign MBA as a standardized commodity (much like the foreign car) with particular use, symbolic and exchange values. However, the limits of the consumption perspective in terms of both consumer sovereignty and subordination are also established in revealing deeper and more dynamic relations of power. Moreover, it is argued that while there are parallels with domestic consumption of MBAs, the teaching of MBAs in Malaysia generates added ambivalence among learners founded on global–local and development–imperialism dynamics and tensions. 相似文献

United States input-output accounts identify and measure the interrelationships between the various industries in the United States economy. However, these accounts do not identify nonprofit activities from their for-profit counterparts in the service-producing sector. This paper, prepared by Gabriel Rudney and Paula Young, presents the methodology and summary data produced by disaggregating the service-producing industries to identify separately nonprofit activities.
The input-output accounts for 1977 produced in this study include 107 industries, but in this paper the results are summarized into 14 industries showing only nonprofit and for-profit components. The GNP and total outputs in this study are consistent with the revised input-output accounts for 1977 prepared by the U.S. Department of Commerce, Bureau of Economic Analysis. 相似文献

This research contrasts the academic literature on key account management (KAM) with the topics in this subject that are most critical to practitioners. Sixty four academic articles published in 17 journals, and ninety practitioners' articles appearing in the Velocity Magazine — published by the Strategic Account Management Association — were content analyzed and classified under ten ‘topic’ categories. Similarities and differences in the results for academics and practitioners are discussed. In addition, two specific topics were identified as being extremely important to managers but still under-researched by academics: the role of senior management in KAM, and the importance of internal alignment in determining KAM success. 相似文献

Many manufacturing firms have multiple manufacturing plants, located in geographically diverse parts of the world. This situation is becoming more common, as firms establish new plants in foreign countries to take advantage of low labor cost. In such cases, it is not unusual for the firm to retain production capability of certain key parts in a backup plant, with the necessary equipment and trained workforce in place. High volume production could be obtained relatively quickly from the backup plant in case of an emergency at the main supplying plant. In such multiplant settings, the transportation costs are significant. Throughout this paper, we use the term “multisourced parts” to describe parts produced in more than one location.Material Requirements Planning (MRP) is the component of a total manufacturing control system that is designed to manage inventory and plan orders for parts and material with dependent demand (demand derived from the demand of other items). Most of the literature on MRP systems discusses MRP methodology in a single-plant environment. Most MRP software systems in use today are single-plant systems.Currently, it is common for firms with multiple plants treated as cost centers to use an independent single-plant MRP system for each and handle the transshipment problems manually. Because of lack of coordination of production schedules between supplying and demanding plants, those firms hold more inventory and experience longer lead times than necessary to compensate for uncertainties in schedules and supply policies.The purpose of this article is to enhance single-plant MRP systems for coping with multiplant situations in which: the plants are regarded as cost centers, there exist multisourced parts, and the transportation costs are significant. The multiplant MRP system should recognize that parts are produced in different plants, make offset calculations for in-transit lead times, and consider transportation costs when establishing production requirements and shipping routes for multisourced parts. The objective is, beginning with the corporate-determined master schedule for finished products, to communicate in one planning cycle time-phased planned order release schedules and shipping/delivery schedules to each manufacturing plant producing components for the finished products.We first present a simplified framework for the multiplant MRP system, where a transportation algorithm is incorporated into the MRP logic. Then we refine this simplified framework to handle more complex aspects of a multiplant network. These complexities include the treatment of requirements that are not shipped on time and the regeneration of new MRP schedules. We also observe that the solution to the transportation problem described above is affected by the lot-sizing rules employed. In addition, we discuss several important issues and decisions that confront a firm when implementing a multiplant MRP system. 相似文献

Yield spreads between mortgage pass-through and U.S. Treasury securities may reflect differences in taxation, phenomena affecting relative supply and demand, and compensation for default, call, and marketability risks on mortgage instruments. Our research empirically models differences in yields between pass-throughs and comparable-maturity Treasuries. We find that interest-rate volatility and the term structure of rates, factors often cited in the mortgage pricing literature as affecting the mortgage call premium, are the primary determinants of movements in these spreads. Moreover, these effects have grown in importance in recent years as exercise of the prepayment option has increased. We also find evidence that liquidity and credit concerns affect the pricing of pass-through securities. 相似文献

The paper first scrutinises the two indices of central bankindependence (CBI) most commonly used in the empirical literature.It defines and discovers an impressive interpretation spread,a major criteria spread but a negligible weighting spread inthose indices Second, it framing the robustness of the empiricalcommon knowledge on the benefits of CBI. It findsthat, when rankings produced by various CBI indices are regressedwith, among others, average inflation, 87 5% of die regressioncoefficients are not statistically significant Third, followingrecent theoretical developments, it suggests an alternativeapproach to the measurement of a central bank's operationalstatus. 相似文献

Krugman, building on the work of Alwyn Young, has argued that hypergrowth in East Asia derives mostly from factor accumulation, owing little to technological change. Yet this explanation is at odds with what analysts of technological change have to say about technology acquisition in these countries. This article examines the Young-Krugman thesis and argues that the problem lies in the misconception of technological change as distinct from accumulation. The critique is taken further by means of a review of the multifaceted way that technology raises the productivity of labor. It is argued that technology is carried not as disembodied knowledge, but as techniques hard-coded in physical devices and structures, by patterns soft-coded in human and organizational capabilities and business-friendly institutions, formal and informal. These operate as symbiotic complements, not separable substitutes as assumed in conventional theory. These arguments are supplemented by perspectives introduced from the technology literature. Since the respective roles and relationship between accumulation and technology are scrutinized, the analysis provides important policy conclusions on the value of East Asian growth strategies. 相似文献
